Somewhere in help usage, we use both "message" and "msg", "command" and "cmd", "key id" and "key-id". This patch makes all help text from parseopt use the first form. Clearer and 3 fewer strings for translators. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
